Many apps cap attachments, often at 25 MB or less. Set a target size under the limit and the file will fit.
Video Compressor
Make a video smaller without uploading it. Choose a quality level or a target size, then download the result. Free, with no signup or watermark.
How to compress a video
Choose your video
Drop an MP4, MOV, WebM or MKV file. Your browser reads it on this device, so nothing is uploaded.
Pick a quality or a size
Choose High quality, Balanced or Smallest, or set a target size in MB. Each level shows its estimated size.
Preview and download
Play the result on the page, see how much you saved, then download it.
When a smaller video helps
Upload it faster
A smaller file takes less time to reach a social app, a website or a client's folder.
Free up storage
Keep a lighter copy of phone videos and long recordings, and move the originals to an archive.
Tips for a good result
- Start with Balanced. Use High quality if you can still see the difference, and Smallest when size matters most.
- Start from the original file when you can. A video that a social app has already compressed loses more quality each time.
- Need the words too? Video to Text turns the same video into a transcript and subtitles.
Video compressor FAQ
Is this video compressor free?
Yes. The compression runs on your own device, so it uses no credits and needs no account. There is no watermark.
Is my video uploaded?
No. Your browser reads the file and compresses it on your device. The video is not sent to our servers, and the result is gone when you close the tab unless you download it.
How much smaller will my video get?
It depends on the file. Phone and camera videos are recorded at a high bitrate, so they usually shrink a lot. A video that was already compressed by a social app shrinks less and loses more quality. Each level shows an estimate, and you can play the result before you download it.
Can I compress a video to a specific size, like 25 MB?
Yes. Choose Target size and enter the size in MB. The tool sets the bitrate and resolution to fit, and if the first pass comes out too large it tries once more. A long video at a very small size will look rough, and the tool tells you when the target is too small for the length.
Which formats can I compress?
You can open MP4, MOV, WebM and MKV files. The result is an MP4 with H.264 video and AAC audio, which plays almost everywhere. A browser that cannot encode H.264 makes a WebM file instead. What your browser can open also depends on its codecs: some browsers cannot read HEVC or ProRes.
Does it work on a phone?
It needs a browser with WebCodecs, such as recent versions of Chrome, Edge and Safari. Speed depends on your device, and the result is held in memory until you download it, so very long videos work better on a computer.
